Demon Lord's Reincarnation

Leo who left after he was done talking with Henrick, that Leo who looked and sounded dominating before, was now breathing heavily under a tree. Though he looked relaxed when facing the enemies, in truth Leo was already pushing Ren's body to its very limits. The techniques he just used were his weakest, some of them weren't even techniques just simple sword slashes, yet it took Ren's body a great deal to do them. 

Leo's slashes were done with perfect synchronization with his body, his mind, his spirit, and his mana. Normally in his own body he wouldn't notice that he was doing this everytime he swung his blades, since his body was so strong that it didn't bother him. Yet now that he was using a weaker body that could not handle such movement, his whole body was in extreme pain. 

At this moment he could not move a single muscle, if someone were to attack him at this moment, they had a slight chance of victory since he couldn't evade. So he casted an illusion spell in the surrounding area. If people pass by they will only see a bunch of trees clustered together. 

'I thought it would be have a bit of fun once I got out and moved a real body. Yet this body of the current incarnation is the weakest one yet. It is true that the amount of mana he holds is pretty huge and it keeps on slowly getting denser, but his physical body is too weak. If he uses spirit aura with this kind of body, it wouldn't help him much. He needs to retrain himself from the ground up.'

Leo continued to grumble about Ren's weak body as he tried to heal himself.

...

Henrick who was left behind with a pile of dead bodies, felt his knees weaken as he fell to the ground. He couldn't believe what had just happened to him. He thought Sepchel was exaggerating, but it turns out he wasn't not one bit. That man called Ren was a monster that could devour everything whole. 

'Damn this, what should I tell my lord? Should I tell him that he should listen to Sepchel and never mess with Ren and his companions again. If we stop now, Ren wouldn't do anything against us. Since in his eyes we are nothing more than bugs.'

Henrick then started to remember the look Ren gave him, as if he was nothing. He treated this whole event like it was just some child's prank. Henrick couldn't help but shiver at that suffocating experience. That smile Ren had all throughout the conversation was unnerving.

Henrick tried relaxing his heavy breathing, trying to calm himself down. He then looked at the bodies of the dead knights and mercenaries littered all throughout the place. 

Upon closer inspection Henrick noticed some things. The shields the knights used were all cut horizontally and it would seem that they were all cut in the exact same manner. Actually all of them, even the dead bodies were slice in half horizontally. 

The time it took for him to receive the message and find Ren, didn't really take that long. That would mean Ren either killed all of these people with blinding speed while using the same move, or he killed them all with one slash. Either way this just proves even more that he was a monster. 

'I know my lord, and I know even if I report what had happened he would never back down. Ren even said those provoking words, if you want to oppose me, sharpen your fangs. No matter what I say, or do not say my lord will still keep on bothering Ren. There must be a way that we can avoid that monster, while at the same time satisfy my lord's wishes.' Henrick left the area with an absent minded look on his face unable to think of a way to deal with the situation. 

...

While Ren was resting somewhere outside of Grenton, his best friend Valdel the cause of all this was walking towards the knight academy with a heavy heart. He set out to find the family members of his schoolmates, but now he returns with nothing to show for. He started thinking of how he should apologize to those schoolmates of his, that was when he remembered something Ren said. 

"Val, you better go back to your school. I'm sure the people you are looking for will show up a bit later."

'That's what Ren said, what did him mean, does he know where the missing nobles are?' While Valdel was trying to figure out, what Ren meant he heard someone calling him, he turned around and saw a familiar face. 

"It's been a long time master." It was Kuro the slave he rescued before.
